lucadelladora – China’s Cyberspace Administration (CAC) recently questioned Nvidia about possible hidden tracking or backdoor features in its H20 AI accelerator. Nvidia firmly rejected these claims, confirming no such mechanisms exist in the product. The company emphasized the critical importance of cybersecurity and assured that none of its devices allow remote access or control. This response followed a formal meeting where CAC raised concerns about potential user data risks tied to the H20 GPU.

China’s scrutiny comes as the U.S. plans legislation requiring advanced chips sold overseas to report their locations. This measure aims to prevent these chips from reaching embargoed regions. The renewed focus on Nvidia’s H20 coincides with the U.S. lifting an earlier export suspension on this GPU, which had been modified to comply with 2023 performance limits.
The H20 is a scaled-down version of Nvidia’s H100 GPU. Unlike fully restricted models, it does not include any hardware tracking modules. Experts note that Nvidia designed the H20 specifically for the Chinese market, responding to tightening U.S. export controls. Despite these controls, Nvidia remains a dominant player in China’s AI hardware market.
China’s Strategic Response and Market Outlook
Industry analysts differ on how aggressively China will pursue the security concerns. Tilly Zhang of Gavekal Dragonomics suggests Beijing views Nvidia’s technology as a bargaining tool, especially as domestic chip alternatives improve. Meanwhile, Charlie Chai from 86Research believes China will mostly apply symbolic pressure, as many local developers depend heavily on Nvidia’s CUDA software platform.
Despite regulatory challenges, including an ongoing antitrust review, demand for Nvidia GPUs remains strong in China. Reuters reports a recent TSMC order of about 300,000 H20 units. Other U.S. suppliers like Micron have also faced similar security investigations, highlighting Beijing’s broader strategy. These probes aim to leverage security concerns while promoting the growth of local semiconductor firms.

So far, the CAC has not announced any specific countermeasures. Analysts expect China to continue importing Nvidia GPUs but under stricter oversight. Meanwhile, the government will likely accelerate investment in home-grown AI chips from companies such as Huawei, Biren, and Cambricon. This dual approach balances the immediate need for advanced hardware with the long-term goal of reducing dependence on foreign technology.
In summary, Nvidia’s denial of hidden features in the H20 GPU highlights ongoing tensions between U.S. export controls and China’s security concerns. The situation underscores the complexities of global technology competition and China’s strategic push to build its domestic AI hardware industry.
